Answer: He sold 10 pounds of cashews .
Step-by-step explanation:
Since we have given that
Selling price of walnuts = $4.00 a pound
Selling price of cashews = $7.00 a pound
Number of pounds of walnuts = 10
Let number of pounds of cashew be x
Total price at which he sold a mixture = $5.50
According to question,
![10\times 4+x\times 7=(10+x)\times 5.50\\\\40+7x=55+5.5x\\\\7x-5.5x=55-40\\\\1.5x=15\\\\x=\frac{15}{1.5}\\\\x=10](https://tex.z-dn.net/?f=10%5Ctimes%204%2Bx%5Ctimes%207%3D%2810%2Bx%29%5Ctimes%205.50%5C%5C%5C%5C40%2B7x%3D55%2B5.5x%5C%5C%5C%5C7x-5.5x%3D55-40%5C%5C%5C%5C1.5x%3D15%5C%5C%5C%5Cx%3D%5Cfrac%7B15%7D%7B1.5%7D%5C%5C%5C%5Cx%3D10)
Hence, he sold 10 pounds of cashews .
